      Description of Alumina Bubble Brick:

       

      Alumina bubble brick adopts Alumina bubble as the main material, high-performance ultra-fine powder as additive and organic binder material. After forming and drying, the alumina bubble products are baked in shuttle kiln at 1750 ℃. The final Alumina Bubble Brick products have the features of light weight, high temperature, small reheating linear change, good thermal shock resistance. It can reduce the costs on kilns build, saving power and widely used in high-temperature furnaces in the field of metallurgy, chemicals, glass, ceramics, refractories and other industries.

      Production of Alumina Bubble Brick:

       

      Add raw aluminum into furnace melted liquid, then pour furnace to make the solution flowing out at set speed, so that the flowing stream form 60 ° -90 °flat nozzle. Blown by high-speed air at pressure 0.6-0.8MPa to form alumina hollow ball. According to a certain proportion, batch hollow ball alumina with sintered alumina powder and binder, Then processed by forming, drying, calcining to obtain alumina bubble brick.

       

      Features of Alumina Bubble Brick:

       

      • High Using Temperature can be above 1750℃ with good thermal stability. Small reheating Linear change rate, longer service life.

       

      • Optimized structure reducing the weight of the furnace:

      The bulk density of alumina bubble brick is only 1.1 ~ 1.5g / cm, the weight can be reduced 1.1-1.9t for 1 cubic meter by using alumina bubble brick.

       

      • Material Saving:

      It can save 80% fire-resistant insulation material by using alumina bubble brick.

       

      • Energy Saving:

      Alumina hollow ball brick has significant insulation properties and low thermal conductivity, which can have a very good insulation effect, reduce heat dissipation, improve thermal efficiency, and thus serve the purpose of saving energy with Energy savings 30%.
